Title: Gas turbine burner
Inventor: MATSUDA KENSHO
IPC: F23R3/30
Filed: 1990-11-30
Abstract: PURPOSE:To reduce temperature distribution and thermal stress and prevent a temperature rise which deteriorates materials by adopting supporting structure of a heavy walled and high rigidity flame stabiliezer in the internal part under thin walled skin structure, protecting the flame stabilizer from deformation and forming a cooling air passage. CONSTITUTION:A heavy walled supporting member 51 which forms a flame stabilizer 4 is fixed with an extended part 55 of a premixer which extends a premixer 6 and its outer peripheral part by means of welds 57 and 54. High pressure cooling air 107 is adapted to flow into the flame stabilizer 4 from the inside of a spring seal 52 passing through a cooling passage 56 installed to the extended part 55 of the premixer. A thin weld 57 and forms 50 is fixed with the premixer 6 by means of the walled outer skin a cooling air passage 59 for the air which has passed by a cooling chamber pore by way of a projection between the flame stabilizer supporting member 51. Therefore, this construction prevents the temperature of the outer skin 50 in direct contact with the flames from an abnormal rise and fails to produce a marked temperature distribution and thermal stress. It is also possible to protect the flame stabilizer 4 from thermal fatigue damage even when there occurs temperature fluctuations caused by swaying flames.
